1 Parallels Virtuozzo Containers Best Practices Alec Istomin, Sr. Sales Engineer

2 Parallels – Optimized Computing TM 2 Agenda 1.Optimize your Virtuozzo infrastructure 2.New Virtuozzo Server Provisioning Best Practices 3.Take Control of Resources Utilization 4.Q & A

3 Parallels – Optimized Computing TM 3 Optimize the Virtuozzo infrastructure Configure Virtuozzo and PIM defaults –Create Container Samples: Resources (SLM), Network Settings, Templates –Create Virtual Networks –Create IP Address Pool –Create Infrastructure and Logical Folders –Connect to your AD Domain –Create and Assign Security Roles –Configure Global Backup Defaults:Storage Location, Type (Incremental) –Schedule Periodic Backups

4 Parallels – Optimized Computing TM 4 Optimize the Virtuozzo infrastructure Linux: Maintain Local Repositories for EZ Templates –Create Linux Distributions Mirrors: createrepo, vzcreaterepo, vzpkgproxy, vzrhnproxy –Create Custom Packages Repository: createrepo –Keep Local Repositories up2date: rsync, createrepo –Configure EZ Templates: /etc/vztt/url.map, repositories, mirrorlist –Configure yum on Virtuozzo Hosts Maintain Local Virtuozzo updates repository –Create in a Container: vzup2date-mirror, VUS (Windows) –Keep up2date –Manual Approval is Possible: (Linux),VUS Manager GUI –Configure on Virtuozzo Hosts: vzup2date.conf (Linux), registry or GUI

5 Parallels – Optimized Computing TM 5 Optimize the Virtuozzo infrastructure Enable scripting across environment –Linux: Use scripting over ssh:.ssh/authorized_keys2 –Windows: Use psexec.exe from Sysinternals –Maintain the text file with Server IP addresses –Run scripts on EVERY Server from a single location –Example: one-liner to install Virtuozzo updates on ALL servers: ▪for i in `cat /root/servers.txt `; do ssh $i "hostname;vzup2date -m batch install --self-update --loader-autoconfig"; done ▪for /F "usebackq" %i in (`cmd /c "more servers.txt"`) do psexec \\%i cmd /c "hostname &vzupdate /unattended"

6 Parallels – Optimized Computing TM 6 New Virtuozzo Server Provisioning Best Practices Unattended Virtuozzo Installation –./install -a -o --skip-reboot -k smp --lic-key XXXXXX-YYYYYY-XXXXXX-YYYYYY-XXXXXX –virtuozzo4.0_x64.exe /L"1033" /V" VZAUTOINSTALL=1 VZ=D:\vz /qr /lv C:\virtuozzo- install.log" Unattended Virtuozzo Updates Installation –Configure Virtuozzo to use Local Virtuozzo updates repository –vzup2date -m batch install --self-update --loader-autoconfig –vzupdate.exe /unattended

7 Parallels – Optimized Computing TM 7 New Virtuozzo Server Provisioning Best Practices Scripting Virtuozzo Post Configuration ▪Install Virtuozzo license: vzlicload –p XXXX-YYYY-XXXX-YYYY-XXXX ▪Virtual networks configuration: vznetcfg ▪Configure container backup defaults, ie location: vzabackup --set-folder /vz/backups/ localhost Linux ▪Configure EZ Templates to use Local packages repository: /etc/vztt/url.map ▪Copy Templates metadata from an existing ‘Master’ Server: tar cfpP - /vz/template/*/*/*/config | (ssh newserver.com tar xfpv - -C /) ▪Cache Templates to ensure that repositories are configured properly: vzpkg create cache Windows ▪Copy and Deploy cached Templates net use z: \\masterserver.com\d$\vz\templates\__cache copy /y "z:\*.efd" "%VZROOT%\templates\__cache" for /F "usebackq tokens=1" %i in (`cmd /c "vzpkgls"`) do vzpkgdeploy -i %i 2>nul

8 Parallels – Optimized Computing TM 8 Take Control of Resources Utilization Monitor your Hardware, Learn Your Peaks and Bottlenecks –PIM - Parallels Infrastructure Manager, will be renamed to PVA (Parallels Virtualization Automation) –perfmon: Virtuozzo object in Windows Performance Counters –vmstat –vzstat –vzslmutilization.sh –/proc/user_beancounters –http://cacti.net/http://cacti.net/ Is it CPU, Disk, Network or Memory ?

9 Parallels – Optimized Computing TM 9 Take Control of Resources Utilization Start from bird’s eye view in PIM

10 Parallels – Optimized Computing TM 10 Take Control of Resources Utilization Inspect a Physical server with high utilization ▪vztop; vzps axfw -E; vzstat; vmstat; vzslmutilization.sh ▪taskmgr.exe; perfmon.exe ▪vzlist -o all Inspect an Abusing Container ▪vzps axfw –E CTID Analyze Processes inside Container ▪strace; ltrace; lsof ▪Sysinternals: procexp.exe; handle.exe Can you tell if it’s an Application Malfunction?

11 Parallels – Optimized Computing TM 11 Take Control of Resources Utilization Tune Virtuozzo Resource Parameters CPU –CPUUNITS –CPULIMIT –CPUS Disk –IOPRIO Network –Shaping Tune the Application Move (temporary?) to Faster Hardware

12 Parallels – Optimized Computing TM 12 Q & A Thank You!
